"So please allow me to go about it in my own way. I will tell you all you want to know to-morrow."

"To-morrow, then."

"May I now continue to unfold my theories?" Bauer nodded and Muller continued: "The criminal wanted Fellner's blood, no matter how."

"Even if it meant murder," said Bauer.

Muller nodded calmly. "It would have been n.o.bler, perhaps, to have warned his victim of his approach, but it might have all come to nothing then. The other could have called for help, could have barricaded himself in his room, one crime might have been prevented, and another, more shameful one, would have gone unavenged."

"Another crime? Fellner a criminal?"

"To-morrow you shall know everything, my kind friend. And now, let us make the trial. Please lock the door behind me as it was locked then."

Muller left the room, taking the pistol with him. Bauer locked the door.

"Is this right?" he asked.

"Yes, I can see a wide curve of the room, taking in the entire desk.

Please stand to one side now."

There was deep silence for a moment, then a slight sound as of metal on metal, then a report, and Muller re-entered the study through the bedroom. He found Bauer stooping over the picture of the French soldier.

There was a hole in the left breast, where the bullet, pa.s.sing through, had buried itself in the back of the chair.

"Yes, it was all just as you said," began the chief of police, holding out his hand to Muller. "But--why the golden bullet?"

"To-morrow, to-morrow," replied the detective, looking up at his superior with a glance of pleading.

They left the house together and in less than an hour's time Muller was again in the train rolling towards the capital.

He went to the goldsmith's shop as soon as he arrived. The proprietor received him with eager interest and Muller handed him the golden bullet. "Here is the golden object of which I spoke," said the detective, paying no heed to the other's astonishment. The goldsmith opened a small locked drawer, took a ring from it and set about an examination of the two little objects. When he turned to his visitor again, he was evidently satisfied with what he had discovered. "These two objects are made of exactly the same sort of gold, of a peculiar old French composition, which can no longer be produced in the same richness. The weight of the gold in the bullet is exactly the same as in the ring."

"Would you be willing to take an oath on that if you were called in as an expert?"

"I am willing to stand up for my judgment."

"Good. And now will you read this over please, it contains the substance of what you told me yesterday. Should I have made any mistakes, please correct them, for I will ask you to set your signature to it."

Muller handed several sheets of close writing to the goldsmith and the latter read aloud as follows: "On the 22nd of November, a gentleman came into my shop and handed me a wedding ring with the request that I should make another one exactly like it. He was particularly anxious that the work should be done in two days at the very latest, and also that the new ring, in form, colour, and in the engraving on the inside, should be a perfect counterpart of the first. He explained his order by saying that his wife was ill, and that she was grieving over the loss of her wedding ring which had somehow disappeared. The new ring could be found somewhere as if by chance and the sick woman's anxiety would be over.

Two days later, as arranged, the same gentleman appeared again and I handed him the two rings.

"He left the shop, greatly satisfied with my work and apparently much relieved in his mind. But he left me uneasy in spirit because I had deceived him. It had not been possible for me to reproduce exactly the composition of the original ring, and as I believed that the work was to be done in order to comfort an invalid, and I was getting no profit, but on the contrary a little extra work out of it, I made two new rings, lettered them according to the original and gave them to my customer.

The original ring I am now, on this seventh day of December, giving to Mr. Joseph Mullet, who has shown me his legitimation as a member of the Secret Police. I am willing to put myself at the service of the authorities if I am called for."

"You are willing to do this, aren't you?" asked Muller when the goldsmith had arrived at the end of the notice.

"Of course."

"Have you anything to add to this?"

"No, it is quite complete. I will sign it at once."

Several hours later, Muller re-entered the police station in his home town and saw the windows of the chief's apartment brilliantly lighted.

"What's going on," he asked of Baner's servant who was just hurrying up the stairs.

"The mistress' birthday, we've got company."

Muller grumbled something and went on up to his own room. He knew it would not be pleasant for his patron to be disturbed in the midst of entertaining his guests, but the matter was important and could not wait.

The detective laid off his outer garments, made a few changes in his toilet and putting the goldsmith's declaration, with the ring and the bullet in his pocketbook, he went down to the first floor of the building, in one wing of which was the apartment occupied by the Chief.

He sent in his name and was told to wait in the little study. He sat down quietly in a corner of the comfortable little room beyond which, in a handsomely furnished smoking room, a number of guests sat playing cards. From the drawing rooms beyond, there was the sound of music and many voices.

It was all very attractive and comfortable, and the solitary man sat there enjoying once more the pleasant sensation of triumph, of joy at the victory that was his alone and that would win him back all his old friends and prestige. He was looking forward in agreeable antic.i.p.ation to the explanations he had to give, when he suddenly started and grew pale. His eyes dimmed a moment, then he pulled himself together and murmured: "No, no, not this time. I will not be weak this time."

Just then the Chief entered the room, accompanied by Councillor Kniepp.

"Won't you sit down here a little?" asked the friendly host. "You will find it much quieter in this room." He pulled up a little table laden with cigars and wine, close to a comfortable armchair. Then, noticing Muller, he continued with a friendly nod: "I'm glad they told you to wait in here. You must be frozen after your long ride. If you will wait just a moment more, I will return at once and we can go into my office.

And if you will make yourself comfortable here, my dear Kniepp, I will send our friend Horn in to talk with you. He is bright and jovial and will keep you amused."

The chief chattered on, making a strenuous endeavour to appear quite harmless. But Kniepp, more apt than ever just now to notice the actions of others, saw plainly that his genial host was concealing some excitement. When the latter had gone out the Councillor looked after him, shaking his head. Then his glance fell by chance on the quiet-looking man who had risen at his entrance and had not sat down again.

"Please sit down," he said in a friendly tone, but the other did not move. His grey eyes gazed intently at the man whose fate he was to change so horribly.

Kniepp grew uneasy under the stare. "What is there that interests you so about me?" he asked in a tone that was an attempt at a joke.

"The ring, the ring on your watch chain," murmured Muller.

"It belonged to my dead wife. I have worn it since she left me,"

answered the unhappy man with the same iron calm with which he had, all these past days, been emphasizing his love for the woman he had lost.

Yet the question touched him unpleasantly and he looked more sharply at the strange man over in the corner. He saw the latter's face turn pale and a shiver run through his form. A feeling of sympathy came over Kniepp and he asked warmly: "Won't you take a gla.s.s of this wine? If you have been out in the cold it will be good for you." His tone was gentle, almost cordial, but the man to whom he offered the refreshment turned from him with a gesture that was almost one of terror.

The Councillor rose suddenly from his chair. "Who are you? What news is it you bring?" he asked with a voice that began to tremble.

Muller raised his head sharply as if his decision had been made, and his kind intelligent eyes grew soft as they rested on the pale face of the stately man before him. "I belong to the Secret Police and I am compelled to find out the secrets of others--not because of my profession--no, because my own nature compels me--I must do it. I have just come from Vienna and I bring the last of the proofs necessary to turn you over to the courts. And yet you are a thousand times better than the coward who stole the honour of your wife and who hid behind the shelter of the law--and therefore, therefore, therefore--" Muller's voice grew hoa.r.s.e, then died away altogether.

Kniepp listened with pallid cheeks but without a quiver. Now he spoke, completing the other's words: "And therefore you wish to save me from the prison or from the gallows? I thank you. What is your name?" The unhappy man spoke as calmly as if the matter scarcely concerned him at all.

The detective told him his name.

"Muller, Muller," repeated the Councillor, as if he were particularly anxious to remember the name. He held out his hand to the detective.

"I thank you, ab, indeed, it thank you," he said with the first sign of emotion he had shown, and then added low: "Do not fear that you will have trouble on my account. They can find me in my home." With these words he turned away and sat down in his chair again. When Bauer entered the room a few moments later, Kniepp was smoking calmly.

"Now, Muller, I'm ready. Horn will be in in a moment, friend Kniepp; I know you will enjoy his chatter." The chief led the way out of the room through another door. He could not see the ghastly pale face of the guest he left behind him, for it was almost hidden in a cloud of thick smoke, but Muller turned back once more at the threshold and caught a last grateful glance from eyes shadowed by deep sadness, as the Councillor raised his hand in a friendly gesture.

"Dear Muller, you take so long to get at the point of the story! Don't you see you are torturing me?" This outburst came from the Chief about an hour later. But the detective would not permit himself to be interrupted in spinning out his story in his own way, and it was nearly another hour before Bauer knew that the man for whose name he had been waiting so long was Leo Kniepp.

The knowledge came as a terrible surprise to him. He was dazed almost.

"And I,--I've got to arrest him in my own house?" he exclaimed as if horrified. And Muller answered calmly: "I doubt if you will have the opportunity, sir."

"Muller! Did you, again--"
